Keep vacuum-operated components receiving their signal at the intended temperature with this Standard Ignition switch, the PVS166 Ported Vacuum Switch. It is a direct-fit replacement for many vehicles, among them the 1980 Chevrolet Citation, 1979-1980 Chevrolet Monza and 1980 Buick Skylark.
A ported vacuum switch uses a thermal element to open or close its vacuum ports as temperature changes. This routes vacuum to the components it controls. Key features of the PVS166:
- Quality control throughout: As a global manufacturer of emission components, Standard maintains quality control across the whole manufacturing process, from componentry to the finished product.
- Brass and high-temperature plastic housing: Carefully constructed to OEM specification for precision fit and performance.
- Feature-rich design: Built with feature-rich design and componentry.
- Specially designed thermal elements: Intended for improved performance.
Signs a ported vacuum switch may need replacing include a cracked housing, a vacuum leak at the switch, or a connected vacuum-operated component that does not switch on or off as temperature changes. Diagnose the cause before replacing, because other vacuum or emissions parts can produce similar symptoms. If a failed switch is the cause, the PVS166 replaces it.
